bad diode can cause this noise i had a funny noise under the hood of my 89 taurus that no one could identify. it varied with engine speed but could not be localized even by a ford technician that i respect. finally on a trip through nebraska i had an occasion to take the car into a ford garage in scottsbluf . i asked if anyone there might know what i had been hearing one of their young technicians came over and pulled off the alternator connector. the noise went away. he explained that when a diode fails the unbalance in the alternator magnetic circuit causes the whine. about 6 months later the alternator had to be replaced and of course the noise was gone. http//www.misterfixit.com/altnoise.htm marsh monster marshmonster2624@aol.com wrote in on aug 4 412pm sorry so...@needadvice.org wrote sorry to keep bugging everyone about this but i just dont know. 77 dodge van 318. on startup ammeter needle swings from full charge to midrange. loud squealing when ammeter needle swings to full charge. noise goes away after engine warms up. i think i tried tightening the belt long time ago and made no difference. visual inspection of belt appears ok. it is one of those kind that is serrated on the pulley side but no glazing or obvious wear. looking at a shop diagnostic report sheet from long ago it is somewhat illegible but says under alternator output bad dode stator which i guess legibly written means bad diode stator would this cause the noise the belt looks ok and i brought the alternator down to autozone for them to test on their machine. test said it was ok but mgr. there said it was probably a bad diode in the alternator. should i buy a new alternator and see if the noise disappears ======= ======= informative diagnostic post.... good for you..... addressing your last question in the post........ no!!!!!!!!!!!!!!!! not yet. the needle should raise on any vehicle momentarily after startup as the generator recharges the battery. fact not fiction i would not condem the altenator yet as long as the charging system seems to be doing its primary job and your main symptom is the noise. keep your money in your pocket for now. now ..as to the topic and your main concerns... being a tech....i wouldnt suspect the stator making the noise but that doesnt eliminate the fact that it still could be the altenator making the noise or the stator for that matter. quite frankly....i dont know. i defer to higher minds which will be with you shortly if youre patient. on closing..... you should be informed that i am not..... a fan of autozonedout parts.....especially electrical anything!! with that said....... still..... jest to see........ you could always....carry it back if the noise didnt go away or..even if it did. and.....i wuddnt feel to baddly bout doin it if i was you...after all.....the dealer techs do it all the time. marshmonster takes a sip of his shroom juice...and tries to remember what the inside of an altenator looked like....20 years ago .
